Mitral valve prolapse: an update.

Abstract: MITRAL valve prolapse (MVP), defined as echocardiographic, angiographic, and pathological protrusion of the mitral leaflets into the left atrium during systole, may affect about 5% of the population and was first widely recognized in the mid-1960s.1-3It is frequently associated with a click and/or murmur. A syndrome consisting of nonspecific symptoms, electrocardiographic abnormalities, and arrhythmias has been recognized by many investigators.1-3Although doubt has recently been expressed about the existence of this syndrome,4-6the complications of MVP,2,7-10albeit rare, earn for it an important place in modern cardiology and may represent its "raison d'etre." Pathology and Etiology Because of the generally benign course of MVP, its underlying pathology has been well documented only in advanced forms that are associated with severe mitral insufficiency and have been termed the "floppy mitral valve."7,8Of great interest has been the demonstration of similar pathological changes in 26 patients

Belly Dancer's Dyskinesia: A Rare Condition.

Abstract: Belly dancer's dyskinesia or diaphragmatic flutter (DF) is a rare condition characterized by repetitive involuntary contractions of the diaphragm. Also known as diaphragmatic myoclonus (DM), this disorder can manifest with involuntary movement of the abdominal wall and contraction of accessory respiratory muscles or respiratory myoclonus. Because of its variable presentation, diagnosis can often be difficult and delayed. This phenomenon is thought to be secondary to abnormal excitation of the phrenic nerve, via the central nervous system or along the nerve.Another possible mechanism is the irritation of the diaphragm itself. Diagnosis can be made with ultrasound, thoracic videofluoroscopy, or electromyography (EMG). Different pharmacologic and surgical therapies have been used in the past, but overall, there are no specific guidelines regarding treatment. In this report, we present a case of DF in a young female patient.

Inadvertent stenting of left main coronary artery complicated by later in-stent restenosis.

Abstract: Stenting of both the protected and unprotected left main coronary artery has been described. This case presents a patient who had inadvertent left main stent deployment. A 47-year-old female presented with a non–Q-wave infarction and subsequent angina leading to angiography and angioplasty of her proximal ramus intermedius artery. Recurrent angina and ECG changes necessitated repeat coronary angiography and angioplasty on the same day with Wiktor stent deployment to treat a resultant dissection. Poststent deployment pictures revealed that the stent had been partially deployed in the left main coronary artery. Additional balloon dilatations were performed at the ostia of the left anterior descending and circumflex arteries through the stent. Three months later the patient presented with progressive angina and was discovered to have severe distal left main stenosis. In a case such as this, stent removal may be preferable to leaving an unnecessary stent within the left main coronary artery. Cathet. Cardiovasc. Intervent. 48:194–197, 1999. © 1999 Wiley-Liss, Inc.
